We empirically explored how creative self-efficacy acts as a mediator in the relationship between knowledge sharing and employee innovation and examined the moderating effects of job satisfaction on this relationship. Matched supervisor-subordinate pairs (N = 274) completed a survey. First, subordinates completed measures of their knowledge sharing, creative self-efficacy, and innovation. Then, the supervisors of these employees assessed their subordinates' responses in terms of innovation. Results showed that knowledge sharing and creative self-efficacy were positively related to employee innovation and that creative self-efficacy mediated the effects of both knowledge sharing and innovation. Finally, job satisfaction enhanced the relationship between creative self-efficacy and employee innovation. We have extended the existing research on individual innovation and we suggest several managerial implications in line with this.

Abstract. The emergence of antibiotic-resistant bacterial strains still remains a significant problem for antimicrobial chemotherapy in the clinic. Bacterial viruses (bacteriophages or phages) have been suggested to be used as alternative therapeutic agents for bacterial infections. However, the efficacy of phage therapy in treating drug-resistant infections in humans is uncertain. Therefore in the present study, we examined the effectiveness of phages in the treatment of imipenem-resistant Pseudomonas aeruginosa (IMPR-Pa) infection in an experimental mouse model. Twenty-nine strains of phage were isolated from our hospital sewage, and phage ØA392 was representatively used for all testing because it has lytic activity against a wide range of clinical isolates of IMPR-Pa. We found that intraperitoneal (i.p.) injections of one IMPR-Pa strain (3x10 7 CFU) caused bacteremia and all mice died within 24 h. A single i.p. inoculation of the phage strain (MOI ≥0.01) at up to 60 min after the bacterial challenge was sufficient to rescue 100% of the animals. This lifesaving effect coincided with the rapid appearance of ØA392 in the circulation (within 2 h after i.p. injection), which remained at substantially higher levels for up to 48 h until the bacteria were eradicated. However, the survival rates of the mice dropped to approximately 50% and 20% when the same dose of this purified phage preparation was administered at 180 min and 360 min, respectively, after IMPR-Pa infections. In addition, we demonstrated that the ability of this phage to rescue bacteremic animals was due to the functional capabilities of the phage and not to a nonspecific immune effect. The protection from death occurred only in animals inoculated with bacteria-specific virulent phage strains. When the heat-inactivated phages were used, the survival rate of the infected mice was dramatically reduced to 20% or lower. Moreover, the levels of the antibody against the phage were not significantly changed at the time when the bacteremic animals were protected by the active phages. Finally, our observations revealed that the inoculation of the mice with high-doses of ØA392 alone produced no adverse effects attributable to the phage. These data indicate that phages can save animals from pernicious P. aeruginosa infections and suggest that phage therapy may be potentially used as a stand-alone therapy for patients with IMPR-Pa infections.

Treatment with infliximab was associated with increased markers of bone formation (BAP) without increasing bone resorption (NTX). This effect may be due to a beneficial effect of TNF-alpha blockade on bone turnover, a beneficial effect on CD activity resulting in decreased glucocorticoid dose, or both. Studies of longer duration are needed to assess the effect of infliximab on bone mineral density.

R-EPOCH therapy does not seem to impact the known poorer prognosis of patients with de novo CD5+ DLBCL, and CD5 expression was still an independent prognostic factor in R-EPOCH-treated patients with DLBCL.

Plant cell walls, which are mainly composed of pectin, play important roles in plant defence responses to pathogens. Pectin is synthesised in a highly esterified form and then de-esterified by pectin methylesterases (PMEs). Because of this, PMEs are directly involved in plant defence. However, the molecular mechanisms of their interactions with pectins remain unclear. In this study, we compared the expression level and enzyme activities of PMEs in a banana Cavendish cultivar (Musa AAA ‘Brazilian’) inoculated with Fusarium oxysporum f. sp. cubense pathogenic races 1 (Foc1) and 4 (Foc4). We further examined the spatial distribution of PMEs and five individual homogalacturonans (HGs) with different degree of pectin methylesterification (DM). Results suggested that the banana roots infected with Foc1 showed lower PME activity than those infected with Foc4, which was consisted with observed higher level of pectin DM. The level of HGs crosslinked with Ca2+ was significantly higher in roots infected with Foc1 compared with those infected with Foc4. Therefore, banana exhibited significantly different responses to Foc1 and Foc4 infection, and these results suggest differences in PME activities, DM of pectin and Ca2+-bridged HG production. These differences could have resulted in observed differences in virulence between Foc1 and Foc4.
